To all whom it may concern.-

Be it known that we, FOKKO H. G. BRANDT, a citizen of Germany, and JOHN R. EvANs, a citizen of the United States reslding at Kansas City, in the county of Wyam dotte and State of Kansas, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to baling presses and more especially to automatic wiring and knotting mechanism therefor, and has for its object to produce a baling press provided with mechanism of the character mentioned which will expeditiously and efi'ectively wire the bales and tie the ends of the wires around the bales securely together.

With this general object in view, the invention consists in certain novel and peculiar features of construction and organlzation as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which Figure 1, is a side elevation of a part of a baling press embodying our invention.

Figs. 31 and 32, are horizontal sections in the plane of the dotted line XXXI of Fig. 3,

Fig. 31 being a sectionthrough the needle mechanism box and Fig. 32 a section through the wire looping and cuttingmechanism box.

In the said drawings, where like reference characters identify corresponding parts in all the figures, 1 indicates a baling case of the customary rectangular form in cross section, 2 is thehopper upon and communicating with the interior of the case to supply the baling material thereto and 3 the reciprocatory head block or plunger for compressing the baling material into bales, any suitable mechanism not shown being employed to operate the head block.

At'opposite sides and just rearward of the hopper with respect to the head block the baling case is provided with a pair of pivotally disposed door-openings 4: normally closed by doors 5 which, as shown in Fig. 9, constitute parts of the side walls of the baling case. maybe termed its front corners with outturned hinge loops 6 and centrally between said hinge loops with a similar loop 6 and said loops each fit between and stand in vertical alinement with a pair of out-turned hinge loops 7 formed integrally with the side walls of the baling case, and connecting each hinge loop with the adjacent pair of wall loops is a hinge pin '8. Between the adjacent ends of said hinge pins 8, longitudinally perforated wire-guide blocks 9 are secured to the side walls of the case, said blocks having ribs 10 which enter openings 11 in the doors when the latter are closed, the said openings being necessary to accom-' modate th ribs 10 which are provided in order that the perforations shall be disposed close to the outer sides of the baling case wall so that the wires 12 may extend close to the walls. The wires lead from spools 13,

mounted in U-shaped brackets 14:, secured to 7 of the cog segments being adapted to carry against the outer sides of the side walls of Each door is provided at what the baling case, and of the same thickness as the vertical flanges of said angle irons are filler blocks 16 and 16" which are secured to the outer sides of the baling case along the vertical margins of the door openings 4. Th filler blocks 16 fit between the wire- .guide blocks 9 and the other filler blocks 16 extend from the lower edge of the vertical grooves -16 and central notches 16, the

notches being provided for the reception and accommodation of transverse stiffenin ribs 16, secured to the outer sides of the doors. The grooves 16 are for the accommodation of the wires 12, as hereinafter explained, and communicate with longitudinal slots 17 in the side walls of the baling case, the wires being adapted to extend from points behind the doors diagonally inward through grooves 1 16 and slots 17 .into the case, so as to guard against any. abrupt bending of the wire when engaged and drawn fromthe spools by the halo in process of formation, as hereinafter more particularly referred to, as such bending of the wire would increase the chances of breakage by producing unnecessary friction betweenthe wires and the baling case.

Referring now to the mechanism for disposing the wire around the bale and then cutting and tying the ends of the wire, 18 are similar boxes open at both ends and arranged in alinement transversely and at opposite sides of the baling case and in communication with the door openings thereof.

The boxes at their inner ends are ofi-set above and below to produce enlargements or extensions 19 and 20 respectively and at their inner ends are provided side flanges 21 and short top and bottom flanges 22, the boxes being secured rigidly to the opposite walls of the baling case by bolts 22.

At the inner edges of filler blocks 16 the inner ends of' the boxes 18 are recessed at 23 for the accommodation of the out-turned hinge loops of the door and walls, as shown clearly in Figs. 9 and 10. The lower walls of the boxes from their inner ends outward for the greater part of their length are provided with wide central slots or openings 24 flanked by depepding bearing lugs 25 forming journal bearings for trunnions 26 of cog segments 27 links 28 being pivotally connected to the lower ends of the cog segments for the purpose of. imparting oscillatory movement thereto through mechanism hereinafter described, the inward movement Lassen boxes.

A third rack bar 33, T-shaped in cross section, is arranged with-its head or flanges resting upon the rack bars 30 of each box,

and its stem fitting snugly between said rackbars. The teeth of all three rack bars of each box are located at the lower edges of such bars and occupy the same horizontal plane but the teeth 34 of rack bar 33 do not extend to the outer end of the bar, as do the teeth on rack bars 30, as will be readily seen by reference to Figs. 3 and 5.

The T-shaped rack bars are provided with recesses 35 at their outer ends and upper sides and secured in said means are brackets 36 carrying pivoted dogs 37 and springs 38 tending to press said dogs upwardly, and said dogs are adapted to reciprocate in slots 39, formed in the top walls of the boxes 18, said slots being covered by plates 40 which are reduced in thickness at their inner ends to provide upward extensions or inverted pockets for the slots 39, the arrangement being such that when the dogs travel inward their full distance, the springs 38 force them upwardly into the pockets 41 and thereby not only positively limit inward movement of the central rack bars 33 but also guard against reverse or outward movement of said rack bars until a direct application of force is imposed upon them to move them outward.

The central rack bars are provided with longitudinal slots 42 and 42 at their outer ends, the slot 42 which is in the rack bar of the looping and cutting mechanism carrying box being shorter than the slot 42 which is in the corresponding rack bar of the needle carrying box, for a purpose which hereinafter appears, and in both cases cross pins 43 extend from the adjacent or flanking rack bars 30 through said slots, as shown clearly in Figs. 3, 4, and 5. It will thus be seen that when the gear segments 27 which engage the teeth of the inner or central rack bars, as well as the flanking rack bars, swing inward, all three rack bars are moved inwardly together and that as the dogs 37 reach the inner ends of the slots 39 and thereby arrest the central rack bars, the gear provided to effect the looping of the ends of the wires and the cutting of the wires before the knots are formed and the extra travel of the needles after the inward travel of the corresponding central rack bar has ended.

It will also be apparent that when the operation of the gear segments is reversed,the central rack bars are held inoperative by the dogs engaging the outer walls of the pockets 41 until the pins 43 reach the outer ends of the slots in the central rack bars, upon which said pins apply positive pressure and thereby overcome the resistance of springs 38 and efi'ect the tripping of the dogs and the outward movement of the central rack bars until all of the rack bars have attained their initial positions, as shown in Fig. 3.

The central or T-shaped rack bars are provided at their inner ends with vertical depending arms 44 having transverse notches 45 in their inner edges for the accommodation of the ribs 16 at the outer sides of doors 5, and the depending arm 44 of the rack bar 33 of the looping and cutting mechanism box 18 is also provided with a pair of notches 46 above and below notches 45, for a purpose which hereinafter appears. The rack bar 33 last referred to is also provided at its inner end with laterally projecting flanges 47 in planes above and below the notches 46, and inthe upper and lower sides of the upper flanges 47/and lower flanges 47 respectively are formed recesses 48, and in both'flanges longitudinal slots 49 are provided, the same registering with the notches 46. Projecting laterally from the inner portion of each depending arm 44, is a door opening arm50 having its outer end rounded at 51 for direct engagement with the proper door so that as the rack bars begin to move inward under the power of the gear segments as hereinbefore explained, the rounded ends of the arms 50 apply pressure upon the ribs 16 of the doors close to the hinges thereof and thereby effect a quick action of the doors, as indicated by dotted lines in Fig. 9, it being also noticed from said figure, that the outer ends of the arms 50 maintain the doors in open position until the reverse movement of the rack bars takes place, upon which the retractile springs 51, tensioned by the opening of the doors, retract and effect the closure of the doors, the said springs being connected to the doors as at 51 and to the adjacent channel tracks 29, as at 51. (See Figs. 9 and 10). In this connection it will be noticed by reference to the same figures, that one of each set of rack bars 30 is provided with a slot 30 for the accommodation of the corresponding door opening arm 50 in the excess inward movement of the rack bars 30 over that of the rack bars 33.

Secured rigidly to the upper and lower sides of the widened or flanked 'portions of rack bar 33 of the box containing the looping and cutting mechanisms are plates 52 terminating at their inner ends in upturned outwardly facing hooks 53, and provided outward of said hooks with laterally projecting pivot pins 54. (See Figs. 20 and 25.)

55 are angle arms provided with longi tudinal slots engaging pins 54 and adapted for movement in a vertical plane in the adjacent recesses 48, (see Figs. 20 and 23) and the slots of said arms are slightly widened or off-set at one end as at 55 for a purpose which hereinafter appears, and adjacent to said widened or off-set ends of the slots the arms are secured rigidly to horizontal shafts 56 journaled in lugs 57 projecting from blocks 58, secured to opposite sides of the inner ends of the rack bars 30. It will be noticed by reference particularly to Figs. 20 and 24, that the said rack bars 30 are provided with extensions at their inner ends, the extensions comprising upright portions 30 and outwardly projecting flanges 30", at the upper and lower margins of portions 30*, and that to the upper flanges 30 upwardly projecting blocks 58 are bolted, it being understood that similar inverted blocks are bolted to the lower flanges 30", as will be understood by reference to Figs. 3, 5 and 6.

59 are arms secured rigidly to the outer ends of shafts 56 vertically over the upper blocks 58 and under the lower or inverted blocks 58, and said arms project toward the baling case and pivotally carry wire-bending forks 60 for entering the flaring pockets 61 of blocks 58. To hold the wire bending forks 60 in position to properly enter the pockets at all times, springs 62 are secured to arms 59 and to said forks. In Fig. 3, the forks 60 are shown as in their normal or elevated position as distinguished from their depressed or operative position, as shown by Figs. 5, 20 and 21.

Inward of the pockets 61, the blocks 58 are provided with upstanding rounded parallel horns 63 spaced apart a suitable distance to permit wires to pass between them, and such spaces open into channels 64 which are alined with similar channels 65 in the portions of the blocks outward of the pockets 61, and said channels 64 and 65 are widened by the provision of V-shaped grooves 66 for a purpose which hereinafter appears, and in this connection it will be noticed by reference to Fig. 20 that the shanks of the forks 60 are at one side of the alined channels 64 and 65 to avoid interfering with the needle operations, hereinafter referred to, and the horns 63 are slightly narrower than the blocks to provide recesses 67, and in their inner faces they are provided with transverse grooves 68 for the holding of the wires while the same are being bent preliminary to the cutting, looping and knotting operations. The tensioning of or pull on the wires by the bale being formed, when the wires are loosely interlocked or knotted to complete the knot, first effects the withdrawal of said knotted ends from pockets 61, but as a precautionary measure, provision is made for the expulsion of the Wires from said pockets, as follows: The blocks 58 are provided with vertical chambers 69 which open through the V-shaped bottoms of the pockets 61 (see Figs. '20 and 22) and are closed at their opposite ends by removable caps 70, and fitting slidiugly in said chambers are pins 71 provided with collars 72, and encircling springs 73 between the caps and collars, which springs normally hold the pins projected into the pockets. When the forks 60 bend the wires into the pockets 61, the pins will be repressed and the springs 7 3 compressed in order that they may, at the proper time, reproject the pins with sufficient force to expel the wires out of the channels 65 and through the spacebetween the looping horns 63. The portions of blocks 58 outward of the pockets are provided with sloping grooves 74, one of said grooves accommodating the free ends-of the wires 12 leading from the spools at the same side of the machine as the wire looping and cutting mechanism box, the groove of the other block 58 accommodating the free ends of the wires leading from the corresponding side of the bale being formed, the wires leading from the bale being numbered 12 for convenience of reference. It is well to state in this connection that there are required at least four spools of wire, two at each side of the baling case, and that the first knot between the two upper wires and the first knot between the two lower wires is tied by hand as indicated by Fig. 14, and that the wires at the opposite sides of the case extend substantially parallel except when suflicient material has been compressed to form a bale of the desired size, and certain operations are then performed either through manual control or automatically to effect inward travel of the various rack bars and the parts carried thereby. When the wires are extending substantially parallel they are disposed as shown most clearly in Fig. 13, that is to say, they extend through the wire guide blocks 9, along the outer surfaces of the doors through the forked guides 5 and then to the material being baled, one pair of the wires however, viz., those at the looping and cutting mechanism box side of the press, extending through guides located adjacent the free edge of the corresponding door 5, and said door is provided with openings 5 to accommodate said guides. The guides are each constructed as follows:

75 is a plate secured by screw bolts 76 to the inner end of the adjacent box 18 and formed with a hook 77 and a pocket 78, and

fitting slidingly in the pocket is a pin 79 held normally y spring 80 against the terminal of hook 77 and projecting sl ghtly out of the pocket. The projecting portion of the pin forms a hook 81 and said hook is beveled at 82 in such a way that a wire under tension between the bale and a spool will, as the door is closed, press sidewise against the beveled surface 82 and efl'ect the repression of the pin into the pocket 78 and pass into the hook 77 and drop back over the hooks 81 so that when the bale is completed and the looping and cuttin mechanism moves inward the wire w1l bend within the said guide around hook 81 in the manner indicated diagrammatically by Fig. 14, this being more clearly understood by reference to Fig. 13, where it is shown as extending through one of said guides.

The pins 79 are provided with laterally projecting arms 83 which project through the side walls of pockets 78 and are pivotally engaged by levers 84 pivoted at 85 to the adjacent box 18 (see Fig. 13) and in the path of movement of tripping cams 86 secured to rack bars 30. By reference particularly to Fig. 26 it will be seen that as one of the cams operates its associated lever 84, the corresponding pin 79 is withdrawn into the pocket 78 and thus permits the wire under tension to spring inwardly, this action being positive because the adjacent ends of the pockets afford resistances which will guard against the wires being drawn into the pockets by the withdrawing pins, as will be readily understood by reference to i Fig. 26.

To dispose the proper wires in the grooves 74 of blocks 58,, the outer walls 74 of said grooves are beveled-at both their inner and the outer sides, being beveled at their outer sides to facilitate the slipping of the tensioned wire from a position approximating the dotted line a in Fig. 14 to the adjacent full line position of said Wire. The bevel on the inner side of said wall is to facilitate the slippage of the wire over said wall after the wire is tied at the rear end of the bale and the latter is ready for discharge from the baling case.

' As the rack bars travel inward, the wires 12 extending from the spools at the right hand side of the press through the guides adjacent the free edge of the contiguous door,

respectively slip over and under the beveled edges 53 of the hooks 53 and snap behind said hooks and are received by the transverse grooves 68 of the horns 63, which horns in their continued inward movement press the intermediate portions of the wires against the hooks 53 and begin to bend said wires at the ends of the intermediate portions, as indicated by dotted lines in the right hand half of Fig. 15, and as these bending actions begin the wires are'cut or severed between the hooks 53. To perform this cutting operation and to subsequently cut the Wires from the spools at the needle box side of the press, blocks 87 fit in notches 46 of the central rack bar 33 and are secured rigidly to and between the flanking rack bars 30 and said blocks are provided with blades 88 slidingly engaging slots 49 of said central rack bar. Each blade is provided with a pair of cutting edges 89 and 90, the former being adapted to sever the wires against the hooks 53 as hereinbefore stated, while the cutting edges 90 are adapted to sever the wires leading from the slots at the opposite side of the press, it being noted by reference to Figs. 3 and 5, that the cutting edges 90 occupy horizontal planes between the planes of the cutting edges 89 so that the cutting edges 90 cannot come into engagement with the wires adapted to be sev ered by the cutting edges 89.

Immediately after the wires are cut by the cuttingedges 89 the cut ends under the inward movement of horns 63 spring across the wires where they bridge the pockets 61, to approximately the position shown in Fig. 16, and as this action occurs the pins 54, through engagement by the outer ends of the slots of angle arms 55, swing said angle arms and cause their forks 60 to engage said ends of the wire and also the adjacent portion thereof and bend the same in the pockets 61, as indicated by Figs. 20 and 22,

'shown, and engaging the Wires at the left hand side of the press between the guides 9 and guides 5 at such side, as shown clearly in Fig. 13. In the inward movement of the rack bars of the needle box, the adjacent door 5 is swung inward as indicated by dotted lines, Fig. 9, as hereinbefore explained, and the needles advancing with the flanking rack bars and the central rack bar, force the wires between guides 9 and 5 across the baling chamber and attain substantially the relative position shown by Fig. 15, as the central rack bar at the opposite side of the press reaches the center line of the press, as indicated by the dotted line in Fig. 15. As the horns move inward until their inner ends are flush with the inner end of the central rack bar and hence with the central line of the press, as indicated in Fig. 16, the rack bars of the needle mechanism box have attained the position shown in Fig. 16, at which time, it will be noted that the ends of the needles have entered the channels 64 of the horns, and the wires between the needles are bearing against the cutting edges 90 of the blades 88, it being likewise noticed by reference to the same figure, that the said wires are pressed by said cutting edges 90 into grooved lugs 93 projecting from certain of the guides 91, as shown most clearly in Figs. 13, 15 and 16. As the wires are thus severed by the cutting ed es 90 of the blades, the inward movement 0 the central rack bar of the needle mechanism box ends. The flanking rack bars 30 however, continue their inward movement and thus slide the needles through the channels 64 of the horns across the pockets 61 and the offset ends of the pivoted forks 60 and then through the channels 65, as indicated by Fig. 17, it being noticed by reference to said figure, that as the needles advance through the channels, the portions of the wires between the needles were doubled back along the sides thereof, the last-named figure being shown partly in section to more clearly disclose the construction last referred to.

Immediately after the operation last de scribed, the needles begin their reverse or outward movement and in withdrawing do not pull the double wires back through the channels because the tendency of the double ends of the wires to spring apart causes them to press against the sides of-the channels 65 with sufiicient force to prevent any frictional contact between them and the needles, from drawing them back with the latter. When the pin 43 attains the outer end of slot 42* the central rack bar begins to move outward also, and when the rack bars and the needles have attained the position shown by Fig. 18, loose knots are formed by the expansion of the balingmaterial. It will be obvious by reference to Fig.

18 when the needles are withdrawn the bale is free to and does impose a pulling strain on the needle-bent ends of the wires and therefore by the time the needle is withdrawn to the position shown in Fig. 18, the said needle-bent ends are drawn back out of the channels 65, and in thus drawing back, their bent back ends pass under the cross looped ends of the wires leading from the bale, over said wires at the opposite side of the crossing point and draw the loops of said wires formed by the horns 63, as shown in Fig. 18, it being noticed that during the insertion and withdrawing of the needles in and from the channels 64: and 65, the rack bars of the looping and cutting mechanism box have remained stationary. Immediately after the actions described have occurred, the outer rack bars of the looping and cutting mechanism box move outward, and in so doing draw the corresponding ends of the wires outward and as said outward movement begins, the pins 54 in the outer or rom the pockets 61 to permit the springrepressed pins 71. to be projected into said pockets and insure the disengagement of the bent looped ends of the wires from the horns, and immediately this occurs, the bale is free to expand to its fullest extent and thereby exert a powerful-pull on the wires in the direction indicated by the arrows, Fig. 19,

\and thereby complete the formation of the knots, Fig. 19, showing a knot almost completed.

Referring now to the mechanism for imparting inward and outward movement to the looping and cutting and needle mechanisms, 94: are guides depending from opposite sides of the baling case, and extending through said guides are the links 28, the inner ends of said links being pivotally connected to tubular guides 95 slidingly receiving cam bars 96 and 97, the former being disposed nearer the vertical plane of the longitudinal center of the press than bar 97, and having a shorter cam or inclined portion than the latter, so that when the cam bars are reciprocated longitudinally, the move ment imparted by the cam bar 96 to the con nected oscillatory segment 27, shall be shorter than the movement imparted by the cam bar 97 to the other oscillatory segment 27, for a purpose which hereinafter appears.

The cam bars 96 and 97 extend through guides 98 depending from the bottom of the baling case, and to cooperate with the guides 98 they are connected by a cross bar 99 carrying a longitudinally extending bar 100 extending through a guide 101 depending from the baling case, and the front end of the cam bars and bar 100 are pivotally connected by links 102 .to a pull bar 103 pro vided with a depending tooth 104, and terminating at its front end in adown-turned hook 105, adapted for engagement under certain conditions by a cross pin 106, carried by depending ears 107 of the head block or plunger 3, the bottom of the baling case having a longitudinal slot 108 to accommodate said ears.

Assuming that wires lead from the spools at opposite sides of the baling case into the latter as hereinbefore explained, and that suflicient material has been compressed in said chamber and against the knotted ends of said wires to form a bale of the required size, the bar 103 is permitted to drop downward until itshook end occupies the plane of the pin 106. Means for performing this function automatically will form the subject matter of a separate application, as the dropping of said bar as described may be controlled manually, Upon the ensuing naeae'ri power stroke of the head block or plunger the pin 106 pushes said bar upward out of the way and then upon the withdrawal stroke of the plunger said pin engages the hook 105 and imparts forward movement to the cam bars. As the cam bars start forward they impart oscillatory inward movement to the two sets of rack bars, the looping and cutting mechanism rack bars moving inward more rapidly than the needle mecha-' The looping and cuta nism box rack bars. ting mechanism rack bars move inward to the center of the press but they'do not travel quite as far as the other rack bars because the latter in their initial positions are disposed a slightly greater distance from the longitudinal center of the press, as will be seen by reference to Figs. 3 and 13, and it will also be apparent by reference to Fig. 2, that after the inward movement of the needle mechanism box rack bar 30 ends, by reason of the segment passing out of gear with the teeth of said bar, the inward movement of the needles continues for the purpose of performing the functions described in connection with the mechanism illustrated more especially by Figs. 13, 15, 16, 17 and 18.

During the looping, cutting and knotting operations described, the doors stand open as indicated more particularly in Figs. 5, 9 and 14the latter in dotted linesand therefore prevent hay passing from the hopper into the baling chamber from interfering with the above mentioned operations, the provisions of the doors therefore avoid.- ing any cessation in the feeding operation and consequent loss of a stroke by the head block or plunger, as upon the ensuing power stroke of the latter the bar 103 is forced rearwardly and through the cam bars, and the other connections described eifects the withdrawal of the rack bars and parts carried thereby, which withdrawal permits the springs 29 to instantly reclose the doors so. that the baling material may have an unobstructed path, it being of course understood that the first charge of baling material is forced by the head block or plunger against the tied wires nearest the hopper and that the additional charges of material supplied for the formation of the next bale cause the spools to pay out the necessary amount of wire.

When the next bale is of the proper size, the operation of the cam bars is again eflected and the operations hereinbefore described are repeated. In view of the fact that the operations of the different parts have been described in connection with the detailed description of parts, it is believed that a recapitulation of the entire operation is unnecessary. While we have described and shown what is at this time deemed the preferred construction of the invention, it is to be understood that we reserve the right to make all changes which properly fall within the principle of construction involved.
